* ixgbe/ixgbevf: Don't use lco_csum to compute IPv4 checksumAlexander Duyck2016-12-01
| | | | | | | | | | | | | | | In the case of IPIP and SIT tunnel frames the outer transport header offset is actually set to the same offset as the inner transport header. This results in the lco_csum call not doing any checksum computation over the inner IPv4/v6 header data. In order to account for that I am updating the code so that we determine the location to start the checksum ourselves based on the location of the IPv4 header and the length.

Emil provides several changes, first simplifies the logic for setting VLAN filtering by checking the VMDQ flag and the old 82598 MAC, instead of having to maintain a list of MAC types. Then made two functions static that are used only within the file, a by-product is sparse is now happy. Added spinlocks to make sure that the MTU configuration is handled properly. Fixed an issue where when SR-IOV is enabled while the ixgbevf driver is loaded would result in all mailbox requests being rejected by ixgbe, so call ixgbe_sriov_reinit() before pci_enable_sriov() to ensure mailbox requests are properly handled. Mark resolves a NULL pointer issue by simply setting the read and write *_ref_mdi pointers for x550em_a devices. Then clearly indicates within ethtool that all MACs support pause frames and made sure that the advertising is set to the requested mode. Fixed an issue where MDIO_PRTAD_NONE was not being used consistently to indicate no PHY address. Alex fixes an issue, where the support for multiple queues when SR-IOV is enabled was added but the support was not reported. With that, fix an issue where the hardware redirection table could support more queues then the PF currently has when SR-IOV is enabled, so use the RSS mask to trim off the bits that are not used. Lastly, instead of limiting the VFs if we do not use 4 queues for RSS in the PF, we can instead just limit the RSS queues used to a power of 2. We can now support use cases where VFs are using more queues than the PF is currently using and can support RSS if so desired. ==================== Signed-off-by: David S.

| * ixgbe: Support 4 queue RSS on VFs with 1 or 2 queue RSS on PFAlexander Duyck2016-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of limiting the VFs if we don't use 4 queues for RSS in the PF we can instead just limit the RSS queues used to a power of 2. By doing this we can support use cases where VFs are using more queues than the PF is currently using and can support RSS if so desired. The only limitation on this is that we cannot support 3 queues of RSS in the PF or VF. In either of these cases we should fall back to 2 queues in order to be able to use the power of 2 masking provided by the psrtype register.

* | net: Update API for VF vlan protocol 802.1ad supportMoshe Shemesh2016-09-24
|/ | | | | | | | | | | | | | | | | | | | | | | | | | Introduce new rtnl UAPI that exposes a list of vlans per VF, giving the ability for user-space application to specify it for the VF, as an option to support 802.1ad. We adjusted IP Link tool to support this option. For future use cases, the new UAPI supports multiple vlans. For now we limit the list size to a single vlan in kernel. Add IFLA_VF_VLAN_LIST in addition to IFLA_VF_VLAN to keep backward compatibility with older versions of IP Link tool. Add a vlan protocol parameter to the ndo_set_vf_vlan callback. We kept 802.1Q as the drivers' default vlan protocol. Suitable ip link tool command examples: Set vf vlan protocol 802.1ad: ip link set eth0 vf 1 vlan 100 proto 802.1ad Set vf to VST (802.1Q) mode: ip link set eth0 vf 1 vlan 100 proto 802.1Q Or by omitting the new parameter ip link set eth0 vf 1 vlan 100 Signed-off-by: Moshe Shemesh <moshe@mellanox.com> Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: David S.

* net_sched: convert tcf_exts from list to pointer arrayWANG Cong2016-08-17
| | | | | | | | | | | | | | | | | | | | | As pointed out by Jamal, an action could be shared by multiple filters, so we can't use list to chain them any more after we get rid of the original tc_action. Instead, we could just save pointers to these actions in tcf_exts, since they are refcount'ed, so convert the list to an array of pointers. The "ugly" part is the action API still accepts list as a parameter, I just introduce a helper function to convert the array of pointers to a list, instead of relying on the C99 feature to iterate the array.

Also the previous patches were always clearing CFIEN which was always set to 0 by the hardware anyway so I am dropping the redundant bit clearing.

Emil fixes the NACK check in ixgbevf_set_uc_addr_vf() for instances where the index is not equal to zero. Fixes an issue where mac->ops.setup_fc can be NULL for backplanes which can cause the driver to crash on load. Don fixes the second parameter of the LED functions, which is the index to the LED we are interested in affecting. Fixed variable to store register reads to unsigned integer. Adds support for the new x553 hardware into ixgbevf. Fixed a missing rtnl lock around ixgbevf_reinit_locked(). Fixed an issue where in ixgbevf_reset_subtask() was not verifying that the port has been removed. Cleans up the initial crosstalk fix, since the SFP that indicates the presence of a SFP+ module changes between hardware types. Babu Moger fixes typo in freeing IRQ, since the array subscript increments after the execution of the statement. Wei Yongjun adds the missing destroy_workqueue() before returning from ixgbe_init_module() in the error handling case. Tony adds range checking for setting the MTU from the VF, where the PF can return a NACK but this was not passed on to the VF, so propagate the results from the PF to the VF so errors can be reported. Consolidates mailbox read and write functions, since the recent changes to ixgbevf_write_msg_read_ack(), other functions are performing the same operations done here. Colin Ian King removes a redundant check on ret_val, since ret_val has not changed since the previous check. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch address a few issues with the initial crosstalk fix. Most important of which is the SDP that indicates the presents of a SFP+ module changes between HW types. With this change that is taken in to consideration It also moves the check closer to the base code that checks link. This makes it so we only need to do the check in one spot.

* | ixgbe: Replace ndo_add/del_vxlan_port with ndo_add/del_udp_enc_portAlexander Duyck2016-06-17
|/ | | | | | | | | | | | | | | | | | | | | This change replaces the network device operations for adding or removing a VXLAN port with operations that are more generically defined to be used for any UDP offload port but provide a type. As such by just adding a line to verify that the offload type is VXLAN we can maintain the same functionality. In addition I updated the socket address family check so that instead of excluding IPv6 we instead abort of type is not IPv4. This makes much more sense as we should only be supporting IPv4 outer addresses on this hardware. The last change is that I pulled the rtnl_lock/unlock into the conditional statement for IXGBE_FLAG2_VXLAN_REREG_NEEDED. The motivation behind this is to avoid unneeded bouncing of the mutex which will just slow down the handling of this call anyway.

* net: define gso types for IPx over IPv4 and IPv6Tom Herbert2016-05-20

These are used to described IP in IP tunnel and what the outer protocol is. The inner protocol can be deduced from other GSO types (e.g. SKB_GSO_TCPV4 and SKB_GSO_TCPV6). The GSO types of SKB_GSO_IPIP and SKB_GSO_SIT are removed (these are both instances of SKB_GSO_IPXIP4). SKB_GSO_IPXIP6 will be used when support for GSO with IP encapsulation over IPv6 is added.

* ixgbe: Fix VLAN features errorAlexander Duyck2016-05-16
| | | | | | | | | | | | | | | | It looks like at some point I somehow transposed the location of setting the VLAN features in netdev->features and the configuration of the vlan_features. As a result the driver is now generating a warning about vlan_features being setup incorrectly. This patch corrects that by placing the update of netdev->features to include the VLAN features so that it is after the point where we write netdev->features into netdev->vlan_features.
